ATTACHMENT FOR CASH-RE GISTERS.

To all whom "it may concern:

Be it known that I, OSCAR K. SLnTTo, of Blackduck, Beltrami county,Minnesota, have invented certain new and useful Improvements inAttachments for Cash-Registers, of which the following is aspecification.

The object of my invention is to provide a phonographic attachment for acash register whereby when a sale is made and the keys are operated torepresent the amount of the purchase the phonograph will audiblyreproduce the amount indicated by the keys.

The invention consists generally in a cash register and a phonographhaving a mechanism actuated by the movement of the keys for setting thephonograph in operation.

In the accompanying drawings, forming part of this specification, Figure1 is a front view partially in section of a cash register with myinvention applied thereto. Fig. 2 is a vertical sectional view on theline aa of Fig. 1. Fig. 3 is an enlarged detail sectional view showingthe operating mechanism between the phonographic records and theregister keys. Fig. 4 is a vertical sectional view on the line bb ofFig. 3.

In the drawings, 2 represents a cash register of ordinary type. I makeno claim to any part of this machine as it corresponds to those now ingeneral use. It is provided with a series of keys 3 also correspondingto those on the cash registers in general use. Upon the top of theregisters I arrange a casing 4 from which the phonographic horn 5projects and below and communicating with the horn are the series ofreproducers 6 also common to phonographic instruments. These reproducersare provided with curved arms 7 having pins 8 which engage the cylinderrecords. A series of rods 9 are vertically movable in guides 10 and areprovided at their lower ends with heads 11 which are engaged byindicator tablets 12 mounted on the cash register keys. In the normalposition of the rods 9 the arms 7 are held out of contact with therecords but when the rods are raised, as by the depression of a registerkey the reproducer arm will be released and the pin will drop down upon.the surface of the cylinder.

11 represents a frame supported upon a central shaft 12 in the casing ofthe phonograph.

13 and 14 are shafts mounted in the frame Specification of LettersPatent.

11 and adapted to revolve in their bearings and also turn with saidframe around the shaft 12. Each shaft 13 and 14 is provided with aseries of record cylinders 15 and 16, representing respectively thedollars and cents keys of the cash register, andv these cyl in ders arearranged so that they will contact with their respective reproducerswhenever a key is depressed and the reproducer repre senting that key isreleased. The shaft 12 is operated by means of a spring 17 having ashaft 18 provided with a thumb nut 19 for winding purposes and a ratchetdevice 20 to prevent backward movement. Pinions 21 and 22 are secured onthe shafts 13 and 14 meshing with an intermediate gear 23 secured on theshaft 12. A pinion 24 is secured on the shaft 12 and meshes with a gear25 that is loosely mounted on the shaft 13 and carries a disk 26 havinga notch 27 in its periphery. A lever 28 is mounted on the shaft 12 andhas a hook 29 adapted to enter the notch 27 and lock the phonographicmechanism against operation.

An arm 30 is provided on the lever 28 and projects outwardly therefrominto the path of a weighted latch device 31 pivoted on the upper end ofa bar 32. This bar extends down through the register, is normally heldin its raised position by a spring 33 and s pivotally connected at itslower end to a lever 34 that has a curved portion 35 in the path of thecash drawer 36. When this drawer is drawn out the tension of the spring33 will oscillate the lever 34, raise the bar 32 to the positionindicated by dotted lines in Fig. 2 to a point above the arm 30. Thenwhen the drawer is shut and engages the curved portion of the arm 35,the bar 32 will be pulled downwardly and the latch device 31 engagingthe arm 30 will trip the lever 28 and release the phonographicmechanism, whereupon the reproducers having been set and allowed tocontact with their respective cylinders through the action of theregister keys will reproduce audibly the amount of the purchase indollars and cents. V

The gear mechanism heretofore described between the central shaft andthe shafts on which the cylinders are mounted, is for the purpose ofreducing the speed and allowing the hook 29 to travel slowly on theperiphery of the disk 26 and reach the notch 27 therein, when thereproducer pin has traversed the surface of the cylinder. There will beample time therefore, before the motion of the mechanism is raised, forthe distinct audible reproduction of the amount of the purchase. A hook37 is provided on the lever 28 and adapted to engage a spring 38 on theshaft 14, when the hook 29 drops into the notch 27 in the disk 26. Inthis position of the lever the cylinder shafts will be locked and willremain in that position until the lever is tripped by the movement ofthe bar 32.

In the position shown in Fig. 2 the cylinders will be stationary, beinglocked by the hooked ends of the lever, the hooks counteracting thetendency of the spring to revolve the cylinder shafts. A fixed brush 39is provided in the casing of the phonographic mechanism for the purposeof keeping the surfaces of the cylinders clean, and brushes 40 areprovided on the frame 17 in position to engage the reproducer pins andkeep them clean also.

I do not in this application wish to be confined to any particular typeof phonograph or mechanism connecting it with the keys of the register,my invention consisting in the appli cation of a phonographic mechanismto a register whereby upon the manipulation of the register keys and theopening and closing of the cash drawer the amount of the purchase indollars and cents will be audibly reproduced.

I claim as my invention 1. The combination witha cash register, of aphonographic mechanism mounted on said register and outside its casing,said mechanism including revolving records and reproducers and meansprojecting within said register casing and normally holding saidreproducers in an inoperative position, said means being actuated by themovement of the register keys to release said reproducers.

2. The combination with a cash register, of a phonographic mechanismdetachably mounted thereon and having records for the dollars and centskeys, mechanism including longitudinally moving locking rods actuated bythe operation of the cash register keys for releasing the phonographicreproducers, and means controlled by the movement of the cash drawer forreleasing the records and starting the phonographic mechanism.

3. The combination, with a cash register, of a phonographic mechanismcomprising records corresponding to the dollars and cents keys, andreproducers having pins, rods arranged to hold said reproducers in aninoperative position but adapted to be operated when the cash registerkey is depressed to release said reproducers, and means actuated by themovement of the cash drawer for releasin the phonographic mechanism andcausing the records to be moved into contact with said reproduce-rs.

4. The combination, with a cash register,

of a phonograph'ic mechanism mounted thereon and having a suitable hornand reproducers, locking rods actuated by the movement of the cashregister key, a revolving frame, records mounted in said frame andcorresponding respectively to the different keys of the register, meansfor revolving said records, means for lockin them in their inoperativeposition, and a bar actuated by the movement of the cash drawer fortripping said locking means and allowing the records to contact withsaid reproducers.

5. The combination with a cash register, of a phonographic mechanismadapted to be mounted thereon outside of the register casing andcomprising revolving records arranged in groups representing the dollarsand cents, reproducers arranged to contact with said records, m ans fornormally holding each reproducer in an inoperative position, said meansprojecting within the register casing and actuated by the movement ofthe register keys.

6. The combination with a cash register, of a phonographic attachmenttherefor, comprising records representing dollars and cents, a springactuated mechanism for revolving said records, reproducers, meansnormally holding said reproducers in an inoperative position andactuated by the movement of the register keys, means for lockin saidspring actuated mechanism and means operated by the movement of the cashdrawer for tripping said locking means.

7. The combination with a cash register, of a phonographic mechanismmounted on said register outside of its casing and comprising revolvingspring actuated records and a series of reproducers arranged to contactwith said records, a brush device arranged to contact with saidreproducers and means for normally holding said reproducers in aninoperative position, said means being actuated by the register keys torelease said reproducers, substantially as described.

8. The combination with a cash register, of a phonographic mechanismmounted thereon and including reproducers, means actuated by themovement of the register keys for rendering said reproducersinoperative, means for locking said phonographic mechanism and meansactuated by the movement of the cash drawer for tripping said lockingmeans and allowing said mechanism to become operative after saidreproducers have been released by the movement of the keys.
